Prospective study about the security and efficacy of treatment without antibiotic therapy of patients diagnosed with acute uncomplicated diverticulitis after launching a protocol at a tertiary hospital.

INTRODUCTION: The main objective of our study is to analyze the results in our hospital after launching a treatment protocol without antibiotic therapy for patients diagnosed with acute uncomplicated diverticulitis. METHODS: Our observational, prospective, single-center study was developed after launching a treatment protocol without antibiotic therapy for patients diagnosed with acute uncomplicated diverticulitis (AUD) in January 2021. The follow-up period was from January 1, 2021 to September 30, 2023. Variables evaluated by the study have included demographic and analytical variables, as well as those related to diagnosis and whether the patients needed to start antibiotic treatment, inpatient treatment, or surgical procedures. RESULTS: In total, 199 patients were diagnosed with AUD, 75 of whom were treated without antibiotic therapy as outpatients. Seven of these patients needed to start antibiotic treatment because of adverse evolution; none of these patients required surgical procedures. The need for inpatient treatment, urgent care, or surgical procedures is similar to the group of patients treated with antibiotics. The main risk factor of failure of outpatient treatment without antibiotic therapy identified by the study was the presence of bacteriuria at diagnosis. CONCLUSIONS: Our results confirm previous reports, observing that treatment without antibiotic therapy in selected patients with AUD is safe.

Diagnostic Accuracy of Abdominal CT for Locally Advanced Colon Tumors: Can We Really Entrust Certain Decisions to the Reliability of CT?

Many different options of neoadjuvant treatments for advanced colon cancer are emerging. An accurate preoperative staging is crucial to select the most appropriate treatment option. A retrospective study was carried out on a national series of operated patients with T4 tumors. Considering the anatomo-pathological analysis of the surgical specimen as the gold standard, a diagnostic accuracy study was carried out on the variables T and N staging and the presence of peritoneal metastases (M1c). The parameters calculated were sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios, as well as the overall accuracy. A total of 50 centers participated in the study in which 1950 patients were analyzed. The sensitivity of CT for correct staging of T4 colon tumors was 57%. Regarding N staging, the overall accuracy was 63%, with a sensitivity of 64% and a specificity of 62%; however, the positive and negative likelihood ratios were 1.7 and 0.58, respectively. For the diagnosis of peritoneal metastases, the accuracy was 94.8%, with a sensitivity of 40% and specificity of 98%; in the case of peritoneal metastases, the positive and negative likelihood ratios were 24.4 and 0.61, respectively. The diagnostic accuracy of CT in the setting of advanced colon cancer still has some shortcomings for accurate diagnosis of stage T4, correct classification of lymph nodes, and preoperative detection of peritoneal metastases.

Emotional Distress Caused by the Measures Taken in Assisted Reproductive Treatments during the COVID-19 Confinement in Spain.

During the pandemic, assisted reproductive treatments suffered from major disruptions in their terms due to the restrictions imposed. The objective of this study is to evaluate the level of anxiety of women whose treatments were either suspended or delayed. METHODS: Descriptive cross-sectional study conducted between April and May 2020. The State-Trait Anxiety Inventory was applied by telephone in a Spanish adapted version. The research also included social, personal, and work aspects which may be involved in the challenging situation. RESULTS: A total of 115 patients participated in the study (73.7%). Women showed a mean in trait anxiety of 17.79 (SD = 8.80) and a mean in state anxiety of 19.95 (SD = 9.08). Neither the type of treatment nor the time of infertility were predictors of trait anxiety or state anxiety. Greater age pressure and more worry were associated to greater trait and state anxiety (p < 0.001). The most common emotional reactions to discontinuation of fertility treatments were sadness and anxiety. CONCLUSIONS: Discontinuation of fertility treatments due to confinement restrictions had a negative impact on the mental health of women who were following a process of assisted reproduction treatment, increasing their levels of emotional distress and anxiety.

Rituximab for the treatment of acute exacerbation of interstitial lung disease associated with connective tissue disease.

BACKGROUND: Acute exacerbation of interstitial lung disease (AE-ILD) is a severe complication with a poor prognosis. No clinical trials have supported the use of rituximab in AE-ILD associated with connective tissue disease. METHODS: We present a series of four cases in which administration of rituximab was associated with appropriate clinical, radiological and functional progress. RESULTS: The four patients were alive 30 days after discharge following their exacerbation. CONCLUSIONS: Given the speed of action, safety and efficacy profile observed for rituximab, we believe that this agent should be further investigated in clinical trials so that it could be included in the daily clinical management of this severe condition.

Crystal structure of (2R*,3aR*)-2-phenyl-sulfonyl-2,3,3a,4,5,6-hexa-hydro-pyrrolo-[1,2-b]isoxazole.

The title compound, C12H15NO3S, was prepared by 1,3-dipolar cyclo-addition of 3,4-di-hydro-2H-pyrrole 1-oxide and phenyl vinyl sulfone. In the mol-ecule, both fused five-membered rings display a twisted conformation. In the crystal, C-H⋯O hydrogen bonds link neighbouring mol-ecules, forming chains running parallel to the b axis.

Acute idiopathic transverse myelitis in children: early predictors of relapse and disability.

OBJECTIVE: To identify early prognostic factors of relapse and disability in children presenting with an acute idiopathic transverse myelitis (TM). METHODS: Ninety-five children with acute idiopathic TM from 2 national European cohorts (France and United Kingdom) of CNS demyelinating diseases in children were identified and studied for early factors that predict relapse and disability using logistic regression models. RESULTS: Sixteen (17%) relapsed, with a diagnosis of multiple sclerosis in 13 (14%) and neuromyelitis optica in 3 (3%). Logistic regression revealed 2 main criteria as risk factors for relapse: female sex (odds ratio [OR] 3.21, 95% confidence interval [CI] 0.88-11.78) and presence of associated brain lesions (OR 14.0, 95% CI 2.8-69.3). Twenty-eight (30%) children had a poor outcome defined by a Kurtzke Expanded Disability Status Scale score ≥4 or an American Spinal Injury Association impairment (ASIA) scale

Video-EEG recordings in full-term neonates of diabetic mothers: observational study.

OBJECTIVE: To determine whether full-term newborn infants of diabetic mothers (IDM) present immature/disorganised EEG patterns in the immediate neonatal period, and whether there was any relationship with maternal glycaemic control. DESIGN AND SETTING: Cohort study with an incidental sample performed in a tertiary hospital neonatal unit. PATIENTS: 23 IDM and 22 healthy newborns born between 2010 and 2013. INTERVENTIONS: All underwent video-EEG recording lasting >90 min at 48-72 h of life. MAIN OUTCOME MEASURES: We analysed the percentage of indeterminate sleep, transient sharp waves per hour and mature-for-gestational age EEG patterns (discontinuity, maximum duration of interburst interval (IBI), asynchrony, asymmetry, δ brushes, encoches frontales and α/θ rolandic activity). The group of IDM was divided into two subgroups according to maternal HbA1c: (1) HbA1c≥6% and (2) HbA1c<6%. RESULTS: Compared with healthy newborns, IDM presented significantly higher percentage of indeterminate sleep (57% vs 25%; p<0.001), discontinuity (2.5% vs 0%; p=0.044) and δ brushes in the bursts (6% vs 3%; p=0.024); higher duration of IBI (0.3 s vs 0 s; p=0.017); fewer encoches frontales (7/h vs 35/h; p<0.001), reduced θ/α rolandic activity (3/h vs 9/h; p<0.001); and more transient sharp waves (25/h vs 5/h; p<0.001). IDM with maternal HbA1c≥6% showed greater percentage of δ brushes in the burst (14% vs 4%; p=0.007). CONCLUSIONS: Full-term IDM newborns showed video-EEG features of abnormal development of brain function. Maternal HbA1c levels<6% during pregnancy could minimise the risk of cerebral dysmaturity.
